Area forecast discussion, Sep 29, 6:00 PM EDT, 5 hours 17 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 600 PM EDT TUE SEP 29 1998 LATEST SATELLITE IMAGES AND RADAR LOOPS SHOW RAIN SHIELD BEGINNING TO MOVE ACROSS THE WESTERN PORTION OF OUR CWA... ESPECIALLY THE SOUTHEAST GEORGIA CWA. A QUICK LOOK AT THE MODELS SHOW THAT THE ETA SEEMS TO HAVE A BETTER HANDLE OF THE SITUATION AS FAR AS PCPN IS CONCERNED. THIS MEANS THAT POPS WILL BE ON THE INCREASE TONIGHT FOR THE SE GEORGIA CWA AND LATE TONIGHT INTO TOMORROW FOR THE NORTH FLORIDA FA. WATER VAPOR LOOP SHOW A BIT OF DRY AIR INTRUSION ACROSS CENTRAL FLORIDA AND THE SOUTHERN PORTION OF OUR CWA. GIVE N THIS SCENARIO...IT LOOKS LIKE WE CAN WAIT UNTIL TOMORROW MORNING TO CONSIDER WEATHER WE SHOULD EXTEND THE FLOOD WATCH EAST INTO THE COASTAL COUNTIES ACROSS NE FL. IF THE ETA VERIFIES... SIGNIFICANT RAIN AMOUNTS COULD SPREAD ACROSS THE ENTIRE CWA TOMORROW. AS FAR AS THE SE GA FA IS CONCERNED...I WOULD CONSIDER PUTTING UP A WATCH TONIGHT AT LEAST FOR THE WESTERN PORTION OF THE CWA AND THEN CONSIDER EXTENDING IT EAST TOMORROW. RADAR ALREADY SHOWS A SIGNIFICANT AREA OF MODERATE TO HEAVY RAIN MOVING TOWARD SOUTH CENTRAL GEORGIA. SANTOS
